What about a Google Wave plugin for Movable Type, as a way to engage in real-time conversations about blog entries. What do think? Below is just a test, you should see an embedded Wave. If you have a Google Wave account, please join the wave and share your thoughts. (I don't have any Google Wave invites, sorry). One of the interesting things about using a Wave for blog comments is that after you join a wave on a blog site, that Wave will show up in your Google Wave inbox going forward. This enables you rejoin the conversation later directly from within Wave. Some bloggers may worry that this may mean less return traffic to their sites, which could be true, but it certainly could boost the amount of discussion around blog entries.
